The interactive multidisciplinary aircraft design code was used for numerical simulation of Tupolev-204 airplane in-flight flutter tests. Dynamic structure loading is generated by symmetric and antisymmetric harmonic excitation of spoilers with smooth frequency sweep from 1 to 5 Hz. Major features of theoretical approach are described. Calculated and experimental results are compared. The influence of unsteady aerodynamic forces and onboard control system on dynamic loading of elastic structure is shown.
